Sweet stuff made from purple yams? (5,5)
I believe the answer is:
maple syrup
'sweet stuff' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'from purple yams?' is the wordplay.
'from' is an anagram indicator (from the letters).
'purple'+'yams'='purpleyams'
'purpleyams' with letters rearranged gives 'MAPLE SYRUP'.
'made' is the link.
Can you help me to learn more?
(Another definition for maple syrup that I've seen is " Sticky (Canadian?) foodstuff".)
